Galvanized SteelComing from the makers of KW
suspension systems the only main difference between the ST Variant 1 and
KW Variant 1 is the steel they use. While KW uses Stainless Steel for
their shock housing, ST uses Galvanized Steel. However, this does not
mean a drop in quality, durability, or appearance. Although coilovers
that use galvanized steel are more prone to corrosion due to
environmental influences (i.e. mixture of salt water); those in the
lower states: California, Texas, Florida, Nevada, etc. don't have to
worry about corrosion. Those in the mid to upper States that snow still
don't have much to worry about as long as they do not drive in heavy
snow conditions upon where salt is used on roads. to further ensure
those with doubt about Galvanized Steel, ST has corrosion resistant zinc
plating on all of their threaded strut housings for further protection.

What is a Coilover?

A coilover suspension basically gives you a matched
lowering spring and shock absorber combination with the added benefit of
adjustable ride height and spring rates through a moveable spring perch
or perches. Coilovers are to your car's advantage by reducing unsprung
mass, increasing suspension travel, and allowing the car to be corner
balanced.
